Have you ever seen a tree stump from a fallen/cut down tree? If you look at it, you can see that the trunk has rings. The number of rings on the tree tells you how old that tree is. Pretty neat, huh?
Dendrochronology is, essentially, a scientific method or way of dating(telling how old) things in the environment. You use this field of study to determine the age of living things, changes in the environment, and growth patterns.
Answer:
pesticides
Explanation:
One major theme of the <em>Silent Spring</em> is the negative power of humans to affect natural world by polluting and making it lethal with the use of pesticides. Carson argues that pesticides have harmful effects on food, on wildlife and on humans. The author gives the example of DDT which is a prime killer and goes on to blame the chemical industry of deliberately spreading wrong information.
The book explores the effects of pesticides on natural ecosystems, on foods that humans consume which lead to cancer and other serious diseases. Critics said that Silent Spring changed the balance of power in the world since many policy changes came into force in the use of DDT and other pesticides and environment-policy changes. <em>Silent Spring</em> helped cause a reversal in the US' national pesticide policy, which led to a nationwide ban on DDT for agricultural uses. It helped create the US Environmental Protection Agency in 1970.

Section three has virtually little that is constructive, yet there are a few instances of kindness mixed in with the violence. The first is a fellow prisoner who gives Elie Wiesel and his father instructions on how to make up their ages in order to remain safe and together.
Elie Wiesel depicts a tragic scenario in the fourth chapter of Night, his account of life in the German concentration camps, in which a handsome young boy, a "pipel," is hanged with two men for the crime of sabotage.
The inmates are used to seeing men hanged, so when a small child is the victim this time, they are horrified to witness it. The youngster is too light to die instantaneously, adding to the horror, so he dies slowly and painfully.
